📋 About This Mod
IMMERSIVE BULLET TIME SFX
Replaces VATS entry and exit sound effects with slowing and speeding heartbeat sound effects respectively. Meant to be used with bullet time mods that use VATS sounds, I personally prefer VAFS Redux.
I made this mod with bad headphones so can't confirm if it sounds good on anything decent.
I would like to make the sound effect last the entire duration of the bullet time, but I don't know how, so this is it. If anyone can give me a pointer, let me know.
